2g ACCELERATION SENSOR
DESCRIPTION
MAS1370P-01 is a
2g acceleration sensor .
The sensor element and the signal processing circuit are inte-
grated in one package, it is small and it can be mounted directly
on a printed board, so it helps reduce the overall size of the sys-
tems.
FEATURES
Capacitive type acceleration sensor
Output ratiometric to supply
16-pin plastic SOP
Wide operation temperature range, small size and lightweight.
APPLICATION
Car Navigation
Projectors
Virtual Reality Input Devices
Inclination Meter
Vibration Measurement
Velocity and Position Measurement
